Enable

IPv6

Field

that

appears

only

for

ACE

module

and

ACE

appliance

software

Version

A5(1.0)

or

later.

Check

box

to

enable

IPv6

on

this

interface.

By

default,

IPv6

is

disabled.

The

interface

cannot

be

in

bridged

mode.

When

you

enable

IPv6,

the

ACE

automatically

does

the

following:

•

Configures

a

link-local

address

(if

not

previously

configured)

•

Performs

duplicate

address

detection

(DAD)

on

both

addresses

Uncheck

the

check

box

to

indicate

that

IPv6

is

disabled

on

this

interface.

IPv6

Global

Address

Field

that

appears

only

for

ACE

module

and

ACE

appliance

software

Version

A5(1.0)

or

later.

A

global

address

is

an

IPv6

unicast

address

that

is

used

for

general

IPv6

communication.

Each

global

address

is

unique

across

the

entire

Internet.

Therefore,

its

scope

is

global.

The

low

order

64

bits

can

be

assigned

in

several

ways,

including

autoconfiguration

using

the

EUI-64

format.

You

can

configure

only

one

globally

unique

IPv6

address

on

an

interface.

When

you

configure

a

gl

obal

address,

t

he

ACE

automatically

does

the

fol

lowing:

•

Configures

a

link-local

address

(if

not

previously

configured)

•

Performs

duplicate

address

detection

(DAD)

on

both

addresses

IPv6

Address

To

configure

an

IPv6

global

address

on

an

interface,

enter

a

complete

IPv6

address

with

a

prefix

of

2000::/3

t

o

3fff::/3.

For

example,

enter

2001:DB8:1::0.

Check

the

EUI-64

check

box

to

specify

that

the

low

order

64

bits

are

automatically

generated

in

the

IEEE

64-bit

Extended

Unique

Identifier

(EUI-64)

format

specified

in

RFC

2373.

To

use

EUI-64,

the

Prefix

Length

field

must

be

less

than

or

equal

to

64

a

nd

the

hos

t

segment

must

be

all

zeros.

Alias

IPv6

Address

When

you

configure

redundancy

with

active

and

standby

devices,

you

can

configure

a

VLAN

interface

that

has

an

alias

global

IPv6

address

that

is

shared

between

the

active

and

standby

devices.

The

alias

IPv6

address

serves

as

a

shared

gateway

for

the

two

ACEs

in

a

redundant

configuration.

You

can

configure

onl

y

one

al

ias

global

IPv6

address

on

an

interface.

To

configure

an

IPv6

alias

global

address,

enter

a

c

omplete

IPv6

address

with

a

pr

efix

of

2000::/3

to

3fff::/3.

For

example,

enter

2001:DB8:1::0.

Note

You

must

configure

redundancy

(fault

tolerance)

on

t

he

ACE

for

the

al

ias

global

IPv6

address

to

work.
